Rhyothemis regia, sometimes called the pied sapphire flutterer, is a species of dragonfly found on islands of the Indo-Pacific region in Indonesia, New Guinea, the Philippines, Taiwan, and more remote Pacific islands such as Samoa and the Northern Mariana Islands.
Rhyothemis regia is placed in the genus Rhyothemis, a group of dragonflies known as "flutterers" placed in the subfamily Sympetrinae, family Libellulidae. The flutterers are known for their large wings with dark coloured markings, and are abundant, forming aggregations or swarms to feed. Rh. regia is sometimes called the "pied sapphire flutterer".
Rhyothemis regia was first scientifically described in the genus Celithemis as C. regia in 1867 by Friedrich M. Brauer. The description was published in a German article titled "Beschreibung neuer exotischer Libellen aus den Gattungen Neurothemis, Libellula, Diplax, Celithemis und Tramea" (transl. Description of new exotic dragonflies from the genera [...]). Brauer described the species' appearance in detail and gave measurements for male and female specimens. The male type specimen is stored in the Natural History Museum, Vienna.
In 1868, Braeur transferred his species... Wikipedia →

With luck
About 10% of wildlife watchers report a Pied Sapphire Flutterer sighting in Taipei on a given day, based on 39 verified sightings from GBIF citizen-science data. It is the 258th most-seen of the 765 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
July and August
In those months about 10% of wildlife watchers report a Pied Sapphire Flutterer in Taipei on a given day, against under 5% in September to June, the lowest months.
Only Taipei, in our data
Taipei is the only city on Wallace's Line with enough records to rate Pied Sapphire Flutterer sightings: about 10% of wildlife watchers there report one on a given day.
Same genus: Rhyothemis
The closest relatives of the Pied Sapphire Flutterer that you can see in Taipei (genus Rhyothemis, Flutterers) are Common Picture Wing (about 10%) and Asian Sapphire Flutterer (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Pied Sapphire Flutterer is recorded against all the insects logged in Taipei (39 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
